Benefits of Using Multiple Tanks to Capture Rainwater

Once you know how many litres of storage you need for your rainwater system, you might naturally then go looking for the one tank that can store all your water. Having two or more tanks in your rainwater harvesting system however can offer a number of advantages.

If the worst happens and your tank springs a leak or one becomes contaminated, then having more than one tank can make the process a whole lot less stressful. Splitting your storage between two or more tanks means that the others could still be used if you have a problem in one. You can fix the problem and you won’t lose all your stored water. This is especially important if you don’t have a back up access to the mains supply.

Also, if you have a growing family, your water usage is likely to rise over the years. Installing two or more smaller tanks from the start makes it much easier to add additional small tanks to suit your usage with relatively little hassle. This spreads the cost of installing storage in your system, reduces unused storage and allows you to be flexible in the future.

Finally, many rainwater tank suppliers are will provide special prices on two or more tanks. So it can actually work out cheaper buying multiple rather than one big tank.

Disadvantages with Multiple Tanks

Of course, there are also some disadvantages you might face with having more than one tank including space requirements and installation complications.

They Need More Space

The most significant difference between a single large tank and two or more smaller tanks is the space needed. You will likely need more space to spread out several tanks for the same storage capacity as a single large tank. If you have a large amount of land, this isn’t a big problem, but for smaller plots it could make a big difference.

However, in some situations where your plot has awkward, un-useable spaces, the ability to install multiple slimline tanks or the like might actually better fit. Smaller tanks can also be hidden more easily with landscaping or behind other structures.

Installation Complications

Installing a series of tanks can take longer and is more complicated. The tanks need to be linked and set up correctly to make sure they work together as a system. If you are having your system installed by professionals, this is not too much of a worry. If you decide a set of smaller tanks is better for you but you’re installing the system yourself, don’t be put off – it is slightly trickier but not impossible and we would be happy to offer you advice.

When you’re deciding if two or more tanks could be the best solution for you, the most important things to check are space and cost.

Tank Dimensions and Space

Once you have measured the space you have available, you can look at rainwater tanks on our website which shows the dimensions of all our small and large tanks.

From these dimensions, you’ll be able to see if you could fit several small tanks in the space you have. Note that the small tanks will need to be placed close to each other so plan for a block of space rather than many separate sites.
